Abstract: Hydrogen energy is an important measure to improve the domestic energy structure and achieve the goals of carbon emission peak and carbon neutrality. Hydrogen storage tanks are one of the key technologies for the development of hydrogen energy. To improve the gravimetric hydrogen densities of hydrogen storage tanks, lightweight type IV tanks with polymer liners have become the key development direction. However, the gas barrier performance of polymer liners has become the core index limiting the development of hydrogen storage tanks. In this paper, the mechanism of graphene improving the gas barrier performance of polymers is expounded, and the theoretical permeation models for two-phase and three-phase composites are summarized. The gas barrier properties of graphene-reinforced polymer matrix composites are outlined based on the chemical structures, modified dispersion, induced polymer crystallization and orientation of graphene. On this basis, future research directions have been prospected.
